Herd Behaviors in the Stock and Foreign Exchange Markets
, 2003 The herd behaviors of returns for the won-dollar exchange rate and the KOSPI are analyzed in Korean financial markets. It is shown that the probability distribution $P(R)$ of price returns $R$ for three values of the herding parameter tends to a power ...

Self-Attracting Walk on Lattices
, 1997 We have studied a model of self-attracting walk proposed by Sapozhnikov using Monte Carlo method. The mean square displacement $ \sim t^{2\nu}$ and the mean number of visited sites $ \sim t^{k}$ are calculated for one-, two- and three-dimensional ...

Nonlinear Stochastic Resonance with subthreshold rectangular pulses
, 2004 We analyze the phenomenon of nonlinear stochastic resonance (SR) in noisy bistable systems driven by pulsed time periodic forces. The driving force contains, within each period, two pulses of equal constant amplitude and duration but opposite signs. Each

Unnormalized nonextensive expectation value and zeroth law of thermodynamics
, 2001 We show an attempt to establish the zeroth law of thermodynamics within the framework of nonextensive statistical mechanics based on the classic normalization $\texttt{Tr}\hat{\rho}=1$ and the unnormalized expectation $x=\texttt{Tr}\hat{\rho}^q\hat{x ...
